初中化学教材中的实验大多是验证型实验这些验证型实验从课题内容、方法、步骤到现象、结论等都是由教材拟定,仅是通过实验证明“果真如此”而已,学生不做实验照样知道结论,无需认真观察,也无需动脑分析其变化的原因及其本质,这样的实验搞多了不利于培养学生的创造能力.与验证型实验不同,探索型实验则是课题由教材或教师拟定,方法、步骤则由学生或师生共同拟定,实验时学生必须认真观察其现象,分析其变化的原因及其本质,才能得出正确的结论.这就大大激发了学生的求知欲,有利于巩固知识、发展智力、培养学生的创造能力.
Most of the experiments in junior high school chemistry textbooks are verification experiments. These verification experiments are based on the content, methods, steps, phenomena, and conclusions of the textbooks. They are only proved through experiments and they do not do experiments. In conclusion, there is no need for careful observation and no brain analysis of the causes and nature of the changes. This type of experiment is not conducive to cultivating students’ creative abilities. Unlike the verification experiment, the exploratory experiment is formulated by the textbooks or teachers. The methods and steps are jointly developed by students or teachers and students. Students must observe the phenomenon carefully during the experiment and analyze the causes and nature of the changes before they can come to a correct conclusion. This greatly stimulates students’ desire for knowledge and helps to consolidate Knowledge, development of intelligence, and cultivation of students’ creativity.
